I recently got my Implanton taking out 4 weeks ago, while it was in for almost 2 years i didnt have a menstrual cycle. 2 weeks after getting it taken out i had a few days were i passed nothing but dime size blood clots i called my doctor but i got no call back it only lasted a few days, the other day i started having clots again with serious cramps. yesterday nothing and today its a suppppper heavy flow changing my tampon every hr. my first question is should i go to the er? and secondly what day should i calcuate being my first day of my cycle the day i started clotting or today with the heavy flow?
